Opis:: The phospholipid-gemini surfactant systems are promising agents for construction of lipoplexes for DNA delivery systems in gene therapy. In this work the influence of a gemini surfactant - 1,1'-(1,6-hexan)bis3-octyloxymethylimidazolium di-chloride) (IMI_Cl_C6_C8) on the structure and phase behaviour of aqueous suspensions of the fully hydrated phospholipid - 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC) were characterised using small angle scattering of synchrotron radiation (SAXS), differential scanning calorimetry (DSC) and Fourier transform infrared spectroscopy (FTIR). The surfactant studied caused a destabilisation of the lamellar phase typical of DPPC. Addition of the surfactant also shifted to lower temperatures and extended the range of the main phase transition

Opis:: The purpose of this study is to discuss the role of kappa-carrageenan (κ-car) in the drying and swelling of polyacrylamide (PAAm)-κ-car composite. The fluorescence intensity of pyranine increased and decreased as drying and swelling time were increased respectively for all samples. The desorption coefficient, $D_{d}$, decreased as κ-car contents were increased for a given temperature during drying. However, cooperative diffusion coefficient, $D_{s}$, increased as κ-car contents were increased during swelling at a given temperature.
